I remember watching this interview and he wasn't specifically talking about GPT4, but just AI progress in general. But I think without a doubt we will see proto-AGI in 2023, or at least an AI model that is so freakishly capable it will be obvious to everyone that AI will change everything. I agree with you that this is an important decade for humanity, and I personally think we will enter a new era of Hope. The hope that everything can be solved with the help of AI. Maybe it's over-optimistic, but I genuinely think this is THE turning point for our species.
